Sillimanite brick is a kind of firebrick made by sillimanite. Sillimanite is calcined at high temperature and converted into mullite and free silica. Generally, high temperature firing method and mud pouring method are used for production.

Features
1.Good wear resistant.
2.Anti-erosion for molten glass, slag, etc.
3.Low thermal expansion.

Application
Sillimanite brick is primarily used for the key parts of the furnace of glass furnace, alkali-free glass fiber furnace, blast furnace hot blast stove and refractory-material tunnel kiln, etc.
